Dear Prof. Garcke, I write to you because I would like to join the "Practical Lab Numerical Simulation - Algorithms in Machine Learning and Their Application" for the next summer semester. I am a Master student and am already familiarized with all the tools you listed on the page of the course. Please let me konw if you need any more information for me to pre-register. I am looking forward for your response. Best, Joel Valdivia Ortega
